    摘要： A method of processing peat for use in treating a contaminated aqueous solution, especially storm water runoff entering a sewer system. The method includes mixing raw peat with heated sulfuric acid to produce a slurry. The slurry is dried and then mixed with a binder medium to produce an aggregate material. The aggregate material is extruded to form a plurality of pellets. The plurality of pellets are then baked in an oven at a temperature in the range of approximately 900-1000 degree F. Peat processed in accordance with the present invention serves as both an ion exchange material as well as an organic retention material. A filter canister for maintaining pelletized peat is also disclosed.

    摘要： A process for absorbing silver from photographic hypo solutions involves passing the hypo solution through a bed consisting of a multitude of a sponge product confined within a vessel. The sponge product is derived from an open-celled cellulosic sponge into which there has been incorporated 30% to 80% by weight of a polymer produced by the thermal interaction of polyethyleneimine (PEI) with a polycarboxylic acid. The polymer further contains an activating multivalent cation and between 90% and 300% water. Silver is eluted from the sponge product employing aqueous solutions of a complexing agent such as an ammonium compound or a cyanide compound. Following a water wash, the bed of sponge product is ready for its next cycle of silver absorption.

    摘要： A method for producing a metal ion exchanger with increased absorption and regeneration capabilities that comprises treating an ionically inert porous support with a solution of metal oxychloride. Said metal oxychloride precipitates within the pores of the support and bonds thereto regardless of the pH of the system. The ion exchanger is then used as a medium through which sea water or other brine solutions are passed and inorganic ions and trace organics selectively absorbed. The ion exchanger is easily regenerated after absorption through treatment with sodium hydroxide and hydrochloric acid and can be reused immediately.

    摘要： Porous granules that contain separate particles of alkali metal silicate and zeolite are stable and are efficient ion exchangers in aqueous effluents and/or solutions. Said granules are heated to provide the stability required so that even though some silicate may dissolve when the granules are exposed to water, the zeolite does not disperse throughout the water.
